GENERAL TERMS AND CONDITIONS (Continued)

2.7 Separation, Dehydration and Processing: If Shipper's gas at a receipt point does

not conform to both Section 2.1(a) and (h), Transporter at its reasonable

discretion may require that some or all of the gas to be transported be processed

to remove liquid and liquefiable hydrocarbons prior to delivery to Transporter or

may require evidence that satisfactory arrangements have been made for the removal

of liquid and liquefiable hydrocarbons at a separation and dehydration and/or

processing plant on Transporter's system. In the event Transporter agrees that

separation and dehydration and/or processing will occur after delivery of

transportation gas to Transporter, Transporter and Shipper shall determine a

mutually agreeable charge for the transportation of liquid and liquefiable

hydrocarbons.

2.8 Waiver of requirements: Transporter may waive the requirements set forth in this

Section 2 in order to allow Shipper to tender or cause to be tendered gas which

does not, when injected into Transporter's pipeline, meet the quality

specifications set forth in Section 2; provided that acceptance of such gas shall

not adversely affect Transporter's system facilities or operations, and further

provided that once such gas has been blended, to the extent blending occurs, the

commingled gas stream at any delivery point on Transporter's system shall meet the

quality specifications set forth in Section 2. Transporter shall post on LINK® any

waiver of Transporter's gas quality requirements. Transporter shall implement this

Section 2.8 on a non-discriminatory basis and may cancel any waiver at any time if

necessary to assure that the commingled gas stream shall not adversely affect

system facilities or operations.

3. MEASUREMENT

3.1 Unit of Measurement: The transportation unit of gas received and delivered by

Transporter shall be a Dekatherm, unless otherwise indicated in this tariff.

3.2 Determination of Volume and Total Heating Value: The volume and the Total Heating

Value of gas received and delivered by Transporter shall be determined as follows:

(a) The unit of volume, for the purpose of measurement, shall be one (1) Cubic

Foot of gas at a temperature of sixty degrees (60() Fahrenheit, and at a

pressure of thirty-three hundredths (.33) pounds per square inch above an

assumed atmospheric pressure of fourteen and four tenths (14.4) pounds per

square inch (fourteen and seventy-three hundredths (14.73) pounds per

square inch absolute pressure).

(b) The Total Heating Value of the gas per Cubic Foot shall be determined by

chromatograph located on Transporter's transmission system, or located so

as to measure the heating value of the gas delivered into Transporter's

transmission system, or any other method mutually agreed upon.

by the ratio of the Total Heating Value of the gas delivered to 1,000. For

purposes of this determination the specific gravity and heating value shall

be determined at approximately the same time.

(d) The temperature of the gas passing through the meters shall be determined

by a temperature transducer, other electronic temperature recording device,

a recording thermometer, or any other method mutually agreed upon, so

installed that it may properly record the temperature of the gas flowing

through the meters.
